Greenspace has become an essential element in the built environment. As a crucial living component, trees in the green space need to be maintained to secure their longevity. In Ternate, information on the green space relating to species diversity, tree performance, and other environment variables is still lacking. One of the important green spaces in Ternate is Nukila Park. The purpose of the study was to describe the species diversity and the physical condition of trees in Nukila Park. Data was collected by recording all three species at the research site and observing their physical condition using visual tree assessment (VTA). Results showed that the tree species are dominated by Pterocarpus indicus , Samanea saman , and S wietenia macrophylla . Diversity index (Shannon Wiener, H’), evenness index (E), and Richness index (Margalef, R) were H’=1.92, E=0.69, and R=2.92, respectively. These values indicate that species diversity and evenness were moderate while species richness was low. The tree health showed that most of the trees (81%) were in good condition, while the rest (19%) were damaged caused by pests and diseases. The results could be used to formulate appropriate management of Nukila Park, such as pest and disease control and species enrichment to improve tree health.
